DESCRIPTION

       The  gnmmanage program can perform various managing operations on geographical networks in
       GDAL. In addition to creating and deleting networks this includes capabilities of managing
       network's features, topology and rules.

       -info  Different  information  about  network:  system and class layers, network metadata,
              network spatial reference.

       create Create network.

              -f <format_name>
                     Output file format name.

              -t_srs <srs_name>
                     Spatial reference input.

              -dsco NAME=VALUE
                     Network creation option set as pair name=value.

       import <src_dataset_name>
              Import layer with dataset name to copy.

              -l layer_name

              Layer name in dataset. If unset, 0 layer is copied.

       connect <gfid_src> <gfid_tgt> <gfid_con>
              Make a topological connection, where the gfid_src and  gfid_tgt  are  vertices  and
              gfid_con is edge (gfid_con can be -1, so the system edge will be inserted).

              Manually assign the following values:

              -c <cost>
                     Cost / weight

              -ic <invcost>
                     Inverse cost

              -dir <dir>
                     Direction of the edge.

       disconnect <gfid_src> <gfid_tgt> <gfid_con>
              Removes the connection from the graph.

       rule <rule_str>
              Creates a rule in the network by the given rule_str string.

       autoconnect <tolerance>
              Create  topology  automatically with the given double tolerance and layer names. In
              no layer name provided all layers of network will be used.

       delete Delete network.

       change Change blocking state of network edges or vertices.

              -bl <gfid>
                     Block feature before the main operation. Blocking features are saved in  the
                     special layer.

              -unbl <gfid>
                     Unblock feature before the main operation.

              -unblall
                     Unblock all blocked features before the main operation.

       <gnm_name>
              The network to work with (path and name).

       <layer>
              The network layer name.
